cellulase production by the fungus trichoderma reesei was studied using sugar beet pulp (sbp) as a substrate. the subculture medium was a salt solution consisting of kh2po4, cacl2, etc. fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°c for 1-2 generations (two days for each generation) and were then used as an inoculum. exponential cells were inoculated into a medium contain...

Cultures of Salmonella subjected to repeated cycles of gamma-irradiation and subculture developed radiation resistance sooner at a low cycling dose ( approximately 1% survival) compared to a high cycling dose ( approximately 0.001% survival). Radioresistant cells in a population of radiosensitive cells of Salmonella newport or S. typhimurium could be selected by the double-irradiation plate met...

It was the goal of this research to examine influence China's young renowned music subcultures. also pointed up difficulties in integrating subculture popular into everyday life. To better understand subcultures and culture, study employed ethnography get a comprehensive understanding cultural social group.

Mature embryos as explants are more convenient to operate and not subjected to time constraints in tissue culture systems. In this research, 120 sorghum varieties were screened to select an appropriate material for establishing a high efficient tissue culture system using mature embryos as explants. Loose, soft, and yellowish primary calluses were induced from the mature embryos of only one var...

Meritec-Strep (Meridian Diagnostics, Inc., Cincinnati, Ohio) a coagglutination method, was compared with Streptex (Wellcome Diagnostics, Research Triangle Park, N.C.), a latex agglutination method, for the identification of beta-hemolytic streptococcal groups A, B, C, F, and G by the direct colony method. A total of 124 beta-hemolytic streptococcal isolates were tested, which included 77 from g...
